92 f250 7.3 non turbo new glow plugs.starts great when cold but after it is shut off for 30 minutes and i go to start it it just spits ang grunts for a second then stalls and wont start.i thought it would be the warm idle or the cold start solenoids.i have a parts truck but i dont know what the solenoids look like.

i am having the same problem. Just bought the truck two weeks ago. it starts right away in the morning, but when i drive it for 10 to 20 miles then part for 30 minutes, it would not start anymore. i replace glow plug relay, fuel filter, checked FSS, replaced two new batteries and still does that routine. I am planning on replacing the starter today am just so frustrated at this point. I drove it once to get to my doctor's appointment, and i ended up towing it back home and yes- all glow plugs are functioning, fuel delivery are good...etc.

The first thing that comes to mind is your guys IP's are on there last leg. As they were the tolerances inside them become "looser". It gets to the point were the tolerances become to much, and when warm (since metal expands) they become even larger. So you try to start and the tolerances are to far apart so the IP can't push fuel out at high enough pressure.

To test: next time this happens take a full water bottle with Luke warm water not ice cold and pour it over the IP. If it starts, because the water cools the case and brings tolerances closer, you knwo you need an new IP.
